“Whether it's after a car crash or it's an active shooter or a stabbing or something of that nature where the paramedics or EMS is not readily on-site, there is still an opportunity for the public to learn how to control bleeding and save lives,” said OHSU trauma surgeon Dr. David Zonies.

He says applying direct pressure is the best way to start, followed by a tourniquet.

If the bleeding doesn't stop, a second tourniquet may be required, followed by packing the wound with gauze or cloth.

“Because uncontrolled bleeding is still the number one cause of preventable death after an injury in the field, what we’re attempting to do is bring this type of education and training to the lay public,” Zonies said.
